Filter by:Background: Multiple myeloma (MM) is a clonal plasma cell neoplasm characterized by proliferation of neoplastic plasma cells in bone marrow (BM). So far, it is an incurable disease and the median survival time of MM patients is only three to four years. Till now, whether the extent of angiogenesis in BM of MM patients serves as an important and independent prognostic factor is still debated. In this study, we would like to have the BM perfusion status imaged by dynamic MRI to mimic the macroscopic vascular densities of BM, and thereafter, the BM perfusion status, the clinical outcome of the MM patients, and the angiogenesis related biological markers will be correlated. Methods: About 35 to 50 MM patients, included newly diagnosed patients or the patients who will undertake the special treatment, are enrolled in this study. The thoraco-lumbar spine is scanned by the MRI, and the BM perfusion status is obtained by contrast-enhanced dynamic MRI. Meanwhile, the patients undertake BM biopsy at one site or two sites and the BM aspirates are also obtained and separated into BM plasma and BM mononuclear cells (BMMC) by Ficoll-Hypaque centrifugation. The angiogenesis related genes expression profiles of the BMMC will be determined by cDNA microarrays and some of them, like VEGF, bFGF, and PDGF, will be semiquantified by real-time PCR. The levels of related proteins will be determined by ELISA. The BM plasma samples are further applied to proteomic analysis to screen the novel molecules with clinical relevance. Prospects: BM perfusion patterns imaged by dynamic MRI can predict the clinical outcome of MM, and are correlated with the angiogenesis relevant biological markers in BM.
The purpose of this study is to determine whether or not cancer cells in the body are affected by PTK and whether it affects the growth of these cells.
The purpose if this study is to evaluate the side effects of the combination of bortezomib and Revlimid (CC-5013) in patients with relapsed and relapsed/refractory multiple myeloma.
Bortezomib (Velcade) has just recently been approved by the FDA for the treatment of multiple myeloma in patients who have received at least two prior therapies and have demonstrated disease progression on the last therapy. This study will determine if Velcade is effective in treating patients with multiple myeloma that have had no prior treatment for the disease. We will also use whole-genome scanning to identify drug response biomarkers in bone marrow samples as well as nerve fiber studies to compare nerves prior to the use of Velcade and after treatment with Velcade.
PRIMARY STUDY OBJECTIVES - To evaluate the efficacy of the combination of clarithromycin (Biaxin®), lenalidomide (Revlimid™), and dexamethasone (Decadron®) as an induction therapy for patients with newly diagnosed multiple myeloma (MM). - To evaluate the safety of the combination of clarithromycin, lenalidomide, and dexamethasone as an induction therapy for patients with newly diagnosed MM. SECONDARY STUDY OBJECTIVES - To examine the role of clarithromycin on the pharmacokinetic properties of dexamethasone and lenalidomide. - To examine the angiogenesis profile in untreated patients and in patients receiving induction therapy.
PRIMARY STUDY OBJECTIVES - To evaluate the efficacy of the combination of bortezomib, dexamethasone, with and without DOXIL, followed by high-dose cyclophosphamide as a therapy for two different subsets of multiple myeloma patients: 1. Patients post first line therapy 2. Patients with relapsed/refractory disease who are bortezomib-naïve - To evaluate the safety of the combination of bortezomib and dexamethasone, with and without DOXIL, followed by high-dose cyclophosphamide as therapy for patients with multiple myeloma. SECONDARY STUDY OBJECTIVES - To evaluate the role of the combination of bortezomib dexamethasone, with and without DOXIL, followed by high-dose cyclophosphamide on the ability to collect > 10 x 106 CD34+ cells/kg in < 7 collections (for both subsets of multiple myeloma patients). - To evaluate the survival of patients who receive the combination of bortezomib dexamethasone, with and without DOXIL, followed by high-dose cyclophosphamide (for both subsets of patients).
The purpose of this study is to determine whether a less-intensive preparative therapy followed by an allogeneic peripheral stem cell transplantation will provide an effective treatment for your disease and whether it will be associated with fewer side effects.
This study is for patients with newly diagnosed or relapsed multiple myeloma. The main purpose of this study is to see how their disease responds to consolidation treatment (treatment aimed at further decreasing cancer cells) with a radioactive antibody (protein) called iodine I 131 tositumomab (known by the tradename Bexxar®) and also to look at the side effects which occur with this type of treatment. The investigators will also be looking at how long disease responds to treatment, if it responds at all, and how long patients who have had this treatment survive. Bexxar is a monoclonal antibody (protein) to which radioactive iodine 131 is attached. The monoclonal antibody in Bexxar (tositumomab), targets a protein called CD20 found on the surface of a variety of B-cells, including lymphoma cells, and some myeloma cells. The antibody is given as an infusion and finds its way to these cells. The radioactive iodine attached to the antibody delivers radiation directly to these cells which works to harm or kill the cancer cells. Approximately 20-25% of patients with multiple myeloma have this protein on the surface of their tumor cells. In addition, this protein was found on the surface of myeloma stem cells. While myeloma stem cells represent a minority of all myeloma cells (less than 5%), these cells are resistant to chemotherapy and are believed to be responsible for a recurrence of the disease after chemotherapy. In this study, Bexxar will be used after patients complete a course of chemotherapy and have residual myeloma cells left in their body. The Investigators are hoping that the treatment with Bexxar will decrease and possibly eliminate residual myeloma cells resistant to chemotherapy.
Patients are being asked to take part in this research study because they have multiple myeloma which has relapsed after (come back), or is refractory to (unaffected by), initial therapy. For patients who have relapsed or are refractory to therapy, there is no agreed upon standard treatment. Treatment options include chemotherapy and, for some patients, bone marrow transplants. None of the available treatments are curative and investigators are continually looking for more effective treatments. This study involves treatment with a new combination of standard drugs: VELCADE, Doxil, and Dexamethasone. Preliminary results from a study using a combination of VELCADE with Doxil showed high response rates (disease reduction). Two other studies showed that an addition of Dexamethasone to VELCADE in patients not responding to VELCADE alone improved response rate. The proposed combination of all three drugs may improve efficacy and response. VELCADE is approved by the Food and Drug Administration (FDA) for use in multiple myeloma. Doxil is not approved for use in multiple myeloma but is an approved drug for use in patients with some other cancers. Several published clinical trials provide evidence that Doxil is an active agent in multiple myeloma and it is used in treatment combinations for multiple myeloma in general practice. Dexamethasone is approved for use in multiple myeloma. The combination of all three drugs is experimental (not FDA approved). The goals of this study are to determine if this new combination therapy with VELCADE, Doxil and Dexamethasone is an effective treatment, and also to determine the side effects that occur when this combination treatment is given.
RATIONALE: Giving chemotherapy before a donor bone marrow transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclophosphamide, mycophenolate mofetil, or tacrolimus after transplant may stop this from happening. PURPOSE: This clinical trial is studying how well giving combination chemotherapy together with tacrolimus and mycophenolate mofetil works in treating patients who are undergoing a donor bone marrow transplant for hematologic cancer.
